Abstract (en)

The present invention relates to a method for making an anvil roll, the method comprising the steps of:providing a cylindrically-shaped body (110) consisting of a first material (118), wherein the first material is selected from the group consisting of: an iron alloy, an aluminum alloy, and a titanium alloy, and wherein the body (110) comprises an outer circumferential surface (102);adding one or more wear resistant materials (120) in the form of powder; andfusing, by applying power from a laser source, the one or more wear resistant materials (118) to the outer circumferential surface (102) of the body (110) to form a plurality of protrusions (180) having a conical or frustro-conical shape comprising tapering sides (182), from a broader base at the outer circumferential surface tapering outwardly towards a narrower tip (185).
